TURN-TAB LE Specification of Letters Patent.

Patented Feb. 4, 1908.

Applicati fil d ilanuary s. 1906. Serial No. 295.034.

.To all whom it may concern:

Be it known that I,HERBERT HASTINGS, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Turn-Tables; and I hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of the specification, and tothe reference-numerals marked thereon.

My present invention relates to turntables and it has for its object toprovide one adapted to be used for supporting vehicles such asautomobiles or other heavy carriages, the parts of which are so arrangedthat the ve- 'cle may be easily run thereon and rotated in a confinedspace.

. My invention has for its further ob'ect to provide a device of thischaracter W 'ch is capable of being readily disconnected and assembledby an unskilled operator thereby enabling it to be packed in smallcompass for shi ment and set up by the user.

To t ese and other ends the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed, the novel features 'bcing pointed out in the claims at the0nd of the specification.

Inthe drawings: Figure 1. is a top plan view of a turntable constructedinaccordance with my invention. Fig. 2 is a side clevation thereof. Fi 3is a longitudinal sectional view on the ine A-A of Fig. 1, and Fig. 4 isa central cross sectional view on the line BB of Fig. 1.

Similar'reference numerals in the several figures indicate similarparts.

A turntable constructed in accordance with my invention comprisesgenerally a platform located in proximity to the surface of V a flooravement and supported upon wheels or ro lers which rotate about axesdisposed radially of a common center, said Wheels being located atdifferent distances from the center of the. platform so that the weightsupported by them will be distributed at ifierent points on the floor,and when the platform is rotated, it will retain its normal centralosition on the floor or pavement. In the pre erred form of my inventionthe platform is composed of two parallel runways A and B which arespacedfrom each other at a distance equal to the standard gage ofvehicles. Each runway comprises a spacing member 1 which is preferablymadeof a plank of a length slightly reater'than the length of the wheelbase of the vehicle for which the device is designed. -At each end ofthe plank is a shoe 2 having a beveled sr1r face 3 extending downwardlyat its forward end from a shoulder 4 which forms an abutment for thebeveled end 5 of the spacing member, which latter is supported upon therearwardly extending end 6 of the shoe. Flanges 7, extend upwardly ateach side of the shoe having the outwardly flaring forward ends and therear ends which are reduced in thickness forming shoulders 9 againstwhich the ends'of the side boards 10 of the spacing members abut. Thelatter may be made integral with the bottom boards or spacin members 1or as separate pieces secured thereto in any suitable manner.

The runways A and B are spaced the required distance from each other bybraces or struts 15, the ends of which engage the proximate sides of theadjacent shoes, and a central brace or strut 16 located midway of thespacing members. Located centrally of the runways is a head 17 providedwith flanges 18, embracing op osite sides of the strut 16, and additionaflanges 19, perforated to receive the free ends of radially extendingtie rods 20 on which are threaded the nuts 21'. from a center common toboth runways and their outward ends extend through perforated lugs 22,located at the inner sides of each of the shoes 2, and are provided withadjusting nuts 23. From the arrangement of the shoes on the spacingmembers and the position of the tie rods, it will be seen that ytightening the nuts 21 and 23 on the latter, the shoes of each runwaywill be drawn inwardly and held tightly in engagement with itsrespective spacing member, and the runways formed by these parts will bemoved relatively toward each other and heldtightly in en agement withthe ends of the spacing members or struts 15 and 16.

-In order to facilitate assembling these parts,

the outer ends of the tie rods pass through apertures'in the struts 15-,servin to temporarily hold the latter in position uring the adjustmentof the rods. The supporting wheels are arranged on each shoe at theirouter and inner sides, those at the inner sides, indicated by 24,

The tie rods extend radially being preferably journaled upon the tierods 20 between the lu s 22. The rollers at the.

outer sides of each runway in alinement with the central strut 16 andjournaled u on brackets 27 secured to the spacin mem ers 1 and theirouter side boards 10. y arranging the rollers as shown, each shoe issupported at opposite sides and as the rollers at the outer side of theshoes are located a greater distance from the center of the platformthan those at the inner sides, they will describe, as'the platform isrevolved, circles of diflerent diameters, thereby distributing the wearon the floor or pavement over a comparatively wide path. Further, theradial position of the 'rollers relatively to the platformflwherebytheir faces lie in planes extending transversely of their respectiverunways, prevents the turntable from creeping when rotatedand fromsliding when the wheels of a vehicle engage the shoes.

The centers of the supporting rollers are located above the floor of theplatform,

enabling the latter to be located in proximity to a floor so that thewheels of a vehicle may be readily run onto the runways. As the assingof a vehicle onto or off from the plat orm may have a tendency todisplace the latter, I provide a central bearing 27 secured to the flooror pavement by suitable devices such as screws or bolts 28, having avertically projecting pin 29 adapted to fit in a central recess providedin the lower side of the head 17 which serves to center the platform.

The upper edges of thebraces or struts 15 and 16 are preferably locatedin alineinent and may be employed as supports "for a removable drippingpan 30.

A turntable constructed in accordance with my invention comprises fewarts which are simple in construction and .w ien assembled produce aplatformwhich is light in weight and substantially rectangular in outline so that when in operative position it occupies a comparativelysmall space and if it is desired to remove the )latforin from the floorit ma be elevated into a vertical position and al owed to rest upon oneof its sides or ends.

I claim as my invention:

1. A turntable for vehicles comprising two parallel connected runwaysadapted to receive the wheels of a vehicle and supporting wheels locatedbetween and at the ends of each runway at theinner and outer sidesthereof and at different distances from the axis of the turntable.

2. A turntable for vehicles comprising two parallel connected runwaysadapted to redownwardly into ceive the wheels of a vehicle andsupporting wheels arranged in pairs at the ends of the .runways, one ofeach of said pairs of supporting Wheels being arranged at an angle tothe runway at the inner side thereof and the other similarly positionedat the outer sideof the runway and at a different distance from the axisof the turn table.

3. In .a turntable, the combination with parallel runways and aplurality of support ing wheels located at the ends of each runway onopposite sides thereof at different distances from a central point andhaving their axes extending radially relatively thereto, and supportingwheels located centrally of the runways on the outer sides of thelatter.

4. In a turntable, the combination with parallel runways each comprisinga spacing member and shoes located at each end thereof, and strutslocated between the runways,
